"If Mexico does not immediately stop ALL illegal immigration to the United States through our southern border, I will close the border or much of the border next week," he tweeted.  The tweets follow a time when the Department of Homeland Security and Border Guard officials said their resources are tense.
In the past two weeks, Customs and Border Guards announced that they will release migrants in Arizona the Del Rio sector and the Rio Grande Valley in Texas. It is expected that more people will be arrested at the border in March than any other month since 2008, says CBP.
Arriving in Florida on Friday afternoon, Trump said he could close the border to act "for a long time," and insisted that the US run out of undocumented immigration detention.
"We have the weakest, most miserable laws," said Trump, threatening to close the border when two current caravans of migrants cross into the United States. "1
" We have no room left. We can not hold people anywhere. Mexico can stop it so easily, "said Trump.
border & # 39; mean?
So far, the Homeland Security Agency's plan is to pull some officers out of legal ports of entry to avoid the influx of A senior official told reporters Friday about a plan to help migrants who were illegally crucified.
The Department of Homeland Security is pulling officers from their ports to join the mission between ports However, the official said the complete closure of the ports of entry is "on the table".
"At the moment of the complete closure of a port, it is short. We will continue to review what is required operationally. But I think what the President is clear is with these numbers, if we have to close ports to take care of all the numbers that come, we'll do that, so it's on the table, "said the official. "What we do, however, is a very structured process based on operational needs to determine how much extra staff we can pull from other tasks to address the crisis between the ports."
The official said that Ministry of Homeland Security search from an operational perspective "and that the Minister of Homeland Security will make a" recommendation to the President ".
Will the closure of the border limit the flow of illegal migrants to the US?
The DHS representative said collaborating with Mexico and relocating resources could limit the flow.
However, part of the crisis seems to be the number of people and families seeking asylum in the US. Asylum seekers are often illegally entered the US to be found and handled by a border official. More staff between the ports of entry can give migrants more visibility after they pass through, but it is unclear whether their presence tends to prevent them from crossing in the first place.
It is also unclear whether the closure is limited to people entering and leaving the US. If cross-border trains and trucks are included that import and export goods with Latin America, closure could pose a significant threat to international trade.
Will Trump repair his threat?
The president seems to point to news coming in the coming weeks at a press event. At least that's what he said this week to Fox News host Sean Hannity.
"In two weeks, I'm going to a place that will be in California, believe it or not, they asked us to build in San Diego, asked us to build a wall, and we're just" We are about to complete a long walk of many kilometers of wall. We're going to hold a press conference there to show people it's really good, "Trump said.
He was also annoyed at a rally in Michigan on Thursday.
Trump tweeted in December that the US "will be forced to completely close the southern border if the obstructed democrats do not give us the money to But he did not close the border at that time.
The president said at the time that "if we find that it is uncontrollable" or it comes to a point where "our people will start to hurt each other, we will enter the country for a period of time close until we can. " Get it under control. "
" The whole border. I mean the whole border, "said Trump.
But again, he did not make up for the threat at the time.
